Problem

You have a supervised model that is not meeting the current benchmark. The raw inputs include numeric, categorical, and timestamp fields, and you suspect the model is missing useful structure in the data.

What matters here

Find transformations that expose signal the model cannot learn directly.
Avoid leaking target information into engineered features.
Validate each change against a stable baseline.
